Fresh coriander is one of the relatively few herbs used in Chinese cookery. It looks like flat-leaf parsley but its pungent, musky, citrus-like flavour gives it a distinctive character which is unmistakable. Often used as a garnish, or chopped and mixed into sauces and stuffings, look for deep green, fresh-looking leaves and substitute with parsley if unavailable. Store coriander by washing, draining, wrapping it in kitchen paper and keeping it in the fridge for several days.
